- Abstract
Despite the discovery of the Higgs boson, the Higgs sector of the standard model is still not fully established. In particular, the self-couplings of the Higgs boson, and its couplings with gauge bosons, are still to be fully determined. We consider electroweak corrections to the process H → ν e ν ̄ e ν μ ν ̄ μ . The corrections depend on the H H H and Z Z H H couplings. We investigate this dependence in κ -framework. We find that the width depends on H H H coupling significantly. The dependence on Z Z H H coupling is only marginal. We also discuss the dependence on Z Z W W coupling.
